Tool/Z whmn it may concern:

Be it known that 1, CHARLES E. BIKER, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented an Improvement in Powder-Guns, of which thefollowing is a specification.

My invention relates to powder-guns commonly employed for blowingpowderupon insects and vermin to exterminate the same and which may beemployed for other purposes.

In carrying out my invention I employ a cylindrical sheet-metal bodyhaving one end fitted with a spring-actuated diaphragm of flexiblematerial to produce a bellows action, the other end of the cylindricalbody being provided with a removable cover. The upper or cover end ofthe body is made rounding and is provided with an adjacent flat portionterminating in an annular inward flange and the cover is made of sheetmetal provided with an annular recess and is preferably of the samediameter as the cylindrical body, so that the flat rim of the coveroverlaps the rounding portion of the body, thereby forming a smallrecess whereby the cover may be readily removed by the finger-nail or asuitable instrument.

The body of the powder-gun is preferably provided with a suitableprojecting nozzle for discharging the powder.

In the drawings, Figure 1 is a general ele-' shown in Fig. 3, by turningthe edge of the rim 1) in against the flexible material, which, however,forms no part of my invention.

For protection and to prevent Wear the diaphragm of flexible material iscentrally provided interiorly and exteriorly with metal disks d e,secured together and to the said material by a rivetf or other means,the disk at being provided with a peripheral flange 2. The upper end ofthe body a is rounding, as indicated at 3, extends inward in a flatadjacent surface, and terminates in an inward inclined annular flange 4.

The cover 7?. may be made of the same material as the body a and isprovided with an exterior annular recess 5, the outer side of whichcorresponds in inclination with the flange 4 of the body and is made ofthe proper diameter to fit snugly within said flange. The diameter ofthe flat rim '5 of the cover It is preferably the same as that of thebody a, so that the said rim overlaps the rounding portion 3 of thebody, thereby forming a small recess 6 between these parts andproviding, a means for easily removing the cover from the body, thefinger-nail or a suitable instrument inserted in this recessaccomplishing this end.

The diaphragm of flexible material is normally held in an extendedposition by the helical spring 7, extending from the upper part of thebody to the disk (1, and the body may be conveniently provided with aproject ing nozzle 8 for discharging the powder.

I claim as my invention 1. As a new article of manufacture, a powder-guncomprising a cylindrical sheet-metal body and a delivery-nozzleprojecting from the side thereof, aspring-actuated diaphragm of flexiblematerial secured to one end of said body and closing the same, with theother end of said body made with a rounded edge or corner and an inwardannular flange, and a cover having an annular portion to fit the flangeof the body and a flat rim overlapping the rounded edge of the body,substantially as specified.

2. As a new article of manufacture, a powder-gun comprising acylindrical sheet-metal body and a delivery-nozzle projecting from theside thereof, aspring-actuated diaphragm of flexible material secured toone end of said body and closing the same, with the other in diameterwith the said b0dy,substantia1ly end of said body made with a roundededge as specified. or corner, a flat adjacent surface and an ad- Signedby me this 30th day of January, jacent inward inclined annular flange,and a 1902. circular sheet-metal cover having an annular CHAS.
